PLEASE HELP ME I am confused
I am more confused with the final answer b≤-11 on a calculator and when I set it up differently, but it's still correct and the calculator gives me b≥-11, but when I solve with pen and paper and show my steps I get b≥-11. The second answer is the same b≥5 either way I'm just confused with the first one. Which way is correct b≤-11 or b≥-11?
Calculator is M a t h w a y

and what would the answer be in interval notation please I would really appreciate it if you can respond as quickly as you can.
